How to find parent product reference in JSON export of bundled orders?

[AlessandroGnola]

Hi everyone.
I have a problem with exporting orders via json and bundles

When opening orders with json

/admin/api/2023-07/orders.json?name=xxxxxx

with bundle products I can't find it  part of

Basically in the order I have the son but I have no reference to the father.
How do I find the reference to the father?

Tnx
